An educational institution issued a degree certificate to those students who have successfully completed all studies included in different levels of the degree program. The degree certificate presented by the University is of major significance in the person's life but the fabrication and circulation of fake certificates is inexpensive because a paper document can easily be forged with the availability of advance printing and copying technologies. So, there is a need to adopt a centralized authentication process that can verify and ensure the authenticity of a document. In order to prevent the spread of fake degree certificates a method is proposed where the integrity of the contents with in the certificate can be verified with the use of and Smart Phone Application. A Quick Response (QR) Code will contain a digital signature over the data such as degree holder's name, major program, Grade Point Average (GPA) obtained etc. Which will be signed by university authorities after the registration in central system and deployed in university. In order to verify the digital signature a person need to use a specific smart phone application which will scan and authenticate the certificate without gaining access to a user's security credentials such as password.

Background: The completeness of cancer registration is a major validity index of any reported cancer incidence. The present study aimed to evaluate the esophageal cancer incidence registered in the Tehran Metropolitan Area Cancer Registry. Materials and methods: The data on esophageal cancer abstracted from three sources of 1) pathology departments, 2) medical records, and 3) death certificates during 2003 till 2007 were utilized. The completeness of the data sources were evaluated using coverage (defined as the proportion of a community population with esophageal cancer identified by the source) and density (defined as the proportion of non-empty fields of the data by source). Results: A total 1,404 cases of esophageal cancer were reported for the duration of the study. Pathology provided 771, medical records 432, and death certificates 609. The coverage was 0.55 for pathology, 0.31 for medical records, and 0.43 for death certificates. The respective density values were 0.82, 0.96 and 0.98, respectively. Pathology (0.45) was the most complete source followed by medical records (0.42), and death certificates (0.29). Discussion: A low degree of completeness dictates putting more effort into case finding plus abstracting data more thoroughly.

The purpose of this study was to analyze the levels of food sanitation knowledge and performance by school food service workers. The data were collected by 440 food service workers in Gyeongbuk province. The collected data were analyzed using the SAS package program (version 8.2 for Window). The results of this study are summarized as follows: 28.6% of the respondents worked in food service at the school where their children attended, 93.6% of the food service workers were part-time employees, and 40.4% had obtained cooking certificates. The food sanitation knowledge scores of food service workers differed significantly according to age (p<0.05), holding of cooking certificates (p<0.01), number of certificates (p<0.01), and whether food service workers is students' parents or not (p<0.01). In addition, the sanitation-performance-degree levels of a few sanitation management items were significantly different according to their food sanitation knowledge level, working time, and whether food service workers is students' parents or not. In conclusion, these factors that improve food service sanitation should be fully considered when food service workers are hired or when food service management policies are established. Additionally, sanitation education and training for school food service workers should be offered regularly with effective education media.

When certificates of qualification relating to computer have shown up like dam water and meeting the age of office automation (OA) utilizing computer throughout the community, and at the point of time when the promotion of efficiency of duty is attempted by utilizing internet, the improvement plans should be groped for to expect to cultivate the national industrial manpower efficiently and by easily approaching the related OA certificates of qualification related to computer so that everyone can acauire the additional points for recognition of credit, entering company and promotion by the dimension of public trust, recognition degree, practial using level in actual affairs, reliability of problems and after manpower management of the certificates of qualification less expensively and saving time. the concrete plans are as follows: First, in the standard of making questions for the examination of 'Computer Utilizing Ability' executed by the chamber of commerce and Industry, there is the independent examination, but by inserting the presentation portion in the higher grade and middle grade, it should be contributed to improve office efficiency both in mane and reality. Second, though the internet retriever's examination is executed by the nongovernment specialized examination, since it is actually widely utilized in the office activities due to universality of using internet, it is now the time to newly establish and accommodate it as the national examination of 'internet Utilizing Ability', not the interest specialized retriever. Third, the applicants, shall take examination for the nongoverment certificate of qualification or enterprise's certificate of qualification at the date and place designated by the applicant, but there are much restrictions for the national certificate of qualification, so the date of examination shall be decided flexibly and efficiently to give chances to students by adjusting to the semesters of the students. Fourth, in this rapidly changing age of the informationalization community, the acquisition of the certificates of qualification through the university and the designated and entrusted educational institutes should be increased the proportion of activation to become officially recognized, and the extent of special treatment for obtainers of the certificate of qualification should be expanded to equip manpower competitive power in the age of informationalization.

Recently, public certificates issued by nationally-recognized certification bodies have been abolished, and internet companies have issued their own common certificates as certification authority. The Electronic Signature Act was amended in a way to assign responsibility to Internet companies. As the use of a joint certificate issued by Internet companies as a certification authority is allowed, it is expected that the fraud damage caused by the theft of public key certificates will increase. We propose an authentication model that can be used in a security gateway that combines PKI with a blockchain with integrity and security. and to evaluate its practicality, we evaluated the security of the authentication model using Sugeno's hierarchical fuzzy integral, an evaluation method that excludes human subjectivity and importance degree using Delphi method by expert group. The blockchain-based joint certificate is expected to be used as a base technology for services that prevent reckless issuance and misuse of public certificates, and secure security and convenience.

This preliminary study examined the degree programs in data science at the School of Information in the States. The focus of this study was the data science degrees offered at the School of Information awarded by the 64 Library and Information Science (LIS) programs accredited by the American Library Association (ALA) in 2022. In addition, this study examined the degrees, majors, minors, specialized tracks, and certificates in data science, as well as the potential careers after earning a data science degree. Overall, eight Schools of Information (iSchools) offered 12 data science degrees. Data science courses at the School of Information focus on topics such as introduction to data science, information retrieval, data mining, database, data and humanities, machine learning, metadata, research methods, data analysis and visualization, internship/capstone, ethics and security, user, policy, and curation and management. Most schools did not offer traditional LIS courses. After earning the data science degree in the School of Information, the potential careers included data scientists, data engineers and data analysts. The researcher hopes the findings of this study can be used as a starting point to discuss the directions of data science programs from the perspectives of the information field, specifically the degrees, majors, minors, specialized tracks and certificates in data science.

This study examined differences in consumers' images of short-term income forest products, preference, willingness to pay prices and purchase behavior according to dietary lifestyle as well as investigated what factors influence the degree of satisfaction when purchasing short-term income forest products and willingness to repurchase. According to dietary lifestyle, the results classified consumers as 'frugal housewife type,' 'convenience-seeking type,' and 'food high-involvement type.' A 'food high-involvement group' is defined as a group that wants high quality products regardless of price. In the 'frugal housewife type,' country of origin and hygiene/safety (considered when purchasing food) had positive influences on the degree of satisfaction. In the 'convenience-seeking type,' country of origin (considered when purchasing food) had a positive influence on the degree of satisfaction while country of origin (checked when purchasing food) had a negative influence on degree of satisfaction. Consumers had a lack of perception for short-term income forest products; subsequently, short-term income forest products had a weakness of low access to consumers. Therefore, farms for short-term income forest products need to divide products into 'high-priced' luxury products and 'low-priced' frugal products according to dietary lifestyle characteristics, improve packaging status to enable consumers to check quality certificates, and clearly indicate country of origin as well as improve distribution processes and increase consumer access to products.
